As someone who is right now working from abroad by necessity - this idea is full of shit.
Yes, you won’t get a chance to properly enjoy your time away, you will always have time constrains (remember - you still need to work, and it’s still on top of your priority list), you will only get to enjoy the country like 2h a day (or whatever you had before as “me” time - that time didn’t change much) .
Assuming you are not going out far from your usual timezone - you will basically only enjoy it in the evenings, and if you are adventurous enough to move very far away from your original timezone - gl, because now you will have all the timezone mess upon you and possibly are working in the unusual hours.
In short: your work will suffer, you will suffer, you won’t get to enjoy your vacation and the country and on top of that - this will cost you more money than you usually pay! What a steal (literally).
Not the one you have been asking, but you can eigher install Lutris, and then install GW2 from there, or download it on Steam. Those are 2 fairly straightforward ways. If you have an ArenaNet account (rather than an account binded to Steam), but still want to use Steam as your launcher - just write “-provider Portal” in launch options.
